ABSORB MORE HEAT
2 Identical Tins or Cans. Black paint. White paint. A paint brush. Water. A Thermometer.
1. Take two identical cans. 2. Using a brush, paint the outer surface of each of the two cans, one with black and the other with white. 3. Fill up water in both the cans and keep it in the sun for an hour. 4. Using a thermometer, measure the temperature of water in both cans.
The water in the can painted black will be warmer than the water in the can painted white.
Why it happens?
Dark colored surfaces particularly black absorbs more heat. While the light shades such as white, reflect most of the heat that falls on them and therefore absorbs less heat. This is the reason why we feel more comfortable wearing white and lighter colored clothes in summer.
